I know it's still Alaska and everything, but it's the middle of MAY for fark's sake. This guy's town is getting 18.5 hours of sunlight every day right now. "Yeah sure, the temperature has been well above freezing every day for a long time and everything's turned to slush, but I'm sure it'll hold the weight!"

I have been told the proper way to do this is to get the dozer going (from shore), rig ropes to the controls and cut-out switch, and let it drive itself across the frozen pond/river. You will of course want someone on the other side waiting to "catch" it.

Anyone ever watch ice road truckers or see the episode of Air Alaska where they drove a dozer over a river? This happens all the time in a safe manner, sometimes mistakes are made. Nothing to see here, move on.
